No mechanical issues your aware of? exhaust leaks will cause a false lean condition if the leak is before the narrowband o2 sensors. Get an 06 5.3 truck tune from the repository and compare everything if you think something is wrong with your tune.
I compared it to my old stock 2006 sierra file, nothing is different on the engine side of the tune. The only thing changed was the gear ratio/tire size and the auto scaled transmission settings along with it.
I would agree with the guy above, check for a mechanical problem. Exhaust leaks, intake leaks because your fuel trims are through the roof. Dirty MAF sensor can cause problems too. If you added a intake system that needs to be adjusted for just like those headers you added.
Once you know everything is working fine, then you can start retuning the VE table and MAF curve with a wideband to bring things back in line. From there you can adjust Power enrichment settings and WOT fueling.
